Fig. 1. Mean total evaporative water loss (A), respiratory evaporative water loss
(B) and cutaneous evaporative water loss (C) (mg H2O g-1
body mass h-1) as a function of air temperature in cool- and
heat-acclimated western white-winged doves Zenaida asiatica mearnsii.
The error bars represent 95% confidence intervals. *Significant
difference between values (P<0.05).

Fig. 2. The contribution of cutaneous evaporation to total evaporative water loss
at three experimental air temperatures in cool- and heat-acclimated western
white-winged doves Zenaida asiatica mearnsii. The error bars
represent 95% confidence intervals. *Significant difference between
values (P<0.001).

heat-acclimated western white-winged doves Zenaida asiatica mearnsii.
The error bars represent 95% confidence intervals. *Significant

Fig. 4. Whole-body water vapour diffusion resistance rv as a
function of air temperature in cool- and heat-acclimated western white-winged
doves Zenaida asiatica mearnsii. The solid lines are linear
regressions fitted to the data. The regression for the heat-acclimated doves
(lower line) is rv=536.59-11.01Ta
(r2=0.634) and that for the cool-acclimated doves (upper
line) is rv=529.06-9.22Ta
(r2=0.395). The slopes of these regressions did not differ
significantly.
